Default Parameters for MySQLCluInEngTest

This test monitors the InnoDB buffer pool on each node of the target MySQL Cluster and reports the amount of memory allocated to the buffer pool and the amount of memory utilized by the buffer pool. The statistics reported by this test help administrators analyze the usage of the buffer pool, and provides them with useful pointers to fine-tune the configuration of the buffer pool.

This page depicts the default parameters that need to be configured for the MySQLCluInEngTest.

• The TEST PERIOD list box helps the user to decide how often this test needs to be executed.

• Specify the name of a database on the target MySQL Cluster database server being monitored in the DATABASE NAME text box.

• To monitor MySQL Cluster database server, the eG agent should be configured with the credentials of a user with server-wide PROCESS and SELECT privileges on the monitored MySQL Cluster database server. To know how to create such a user, refer to Pre-requisites for Monitoring the MySQL Cluster Database Server topic. Specify the name and password of such a user in the USER NAME and PASSWORD text boxes.

• Confirm the Password by retyping it in the CONFIRM PASSWORD text box.

• Once the necessary values have been provided, clicking on the UPDATE button will register the changes made.

When changing default configurations of tests, the values with “$” indicate variables that will be replaced by the eG system according to the specific server being managed - for instance, $hostName is the host/nickname of the target host, $port is the port number of the server being monitored. E.g., for a server xyz:80, $hostName will be changed automatically by the eG manager to “xyz*” and $port will be changed to “80” when configuring a test.
